FIRE- GRATE OR FIREPLACE.

SPECIFICATION forming part of Letters Patent No. 757,595, dated April 19, 1904;.

I Application filed *anaary 31, 1903. Serial No. 141,321. No model.)

To all whozrt itincty concern:

Be it known that I, Fnnnnmon JAMES Bos- TEL, a subject of Edward, King of Great Brit aim and Ireland, residing at 73. Ebury street, in the city of Westminster, in the county of London, England, have invented certain new and useful Improvements Relating to Fire- Grates or Fireplaces, of which the following is a specification.

The present invention relates'to fire-grates or fireplaces, especially for use in sittingroomsor for general purposes; and it consists of certain improvements whereby the fuel can be burned to much greater advantage and smoking into the room, which so frequently happens when a fire is first lighted,'can be practically overcome.

According to my invention 1 construct a fire-grate with a sloping back, preferably firebrick, which is normally inclined forwardly, so as to deflect the heat into the room. It may be hinged at the bottom, so as to be capable of being swung back rearwardly to a diiferent angle or, if desired, to a vertical position. The back may be rigidly connected to the bot tom of the grate, so that the latter will move radially to an inclined position when the back is swung rearward, the angle between them remaining the same. The sides or cheeks may be in the angle between the grate and back or may be built into the stationary part of the fireplace, as may be found more convenient.

The grate or hearth may be of slow, medium, or fast combustion type and may be mounted above any suitable form of ash-box. Fire-bars may be fitted at the front, if needed. Also a blower or canopy andastove, overmantel, or any other accessories may be coinbined with my invention.

I may construct my fireplace or grate from angle iron, suitably formed to receive the molded slabs or bricks of fire-clay at the back.

and, if desired, the sides also. The hearth may be either grated or perforated or solid. In one form the ash-boxmay be a receptacle upon the back of which is situated the hinge or hinges carrying the grate and back. If

needed, a ratchet or equivalent means may be employed to hold the grate at the desired anlittle or no black smoke given off, and Fig.

2 the same in perspective. Fig. 3 is a side view of the grate when partly tilted back to quicken the fire and prevent smoke escaping except up the chimney. Fig. 4 is a front elevation of same.

' Referring to said drawings. A A represent the sides or checks of the grate united to one another at the rear by cross-bars B or by a back, there being also a heat-radiating slab C, of fire-clay or other refractory material, which may be held against a rabbet D or against a strip or projections on the inner sides of the cheeks A. The front tops of the sides are joined by a front rail E, and the general shape of the sides is such as to allow the grate to hang or rest upon supports permitting it to be tilted either forwardly or rearwardl y. The supports in the form shown consist of raised crescent-shaped pieces F, (one on each cheek,) adapted to be carried within a concavity in the top edge of side supports Gr, somewhat like a trunnion-bearing. The firebars H are preferably straight when seen frontwise and curved when viewed sidewise, forming a bottom and a front combined, the cheeks A being curved likewise on their front and bottom edges. The front of the ash-box J and the sides of same adjacent thereto are shaped so as to close thespace below the firebars against the admission of air when the grate is in the position shown in Figs. 1 and 2, thus causing slow combustion. The grate sides may carry eyeleted lugs K, into which a poker is inserted, by which means the inclination of the grate can be altered with the greatest ease.

Any other form of hinge may be employed for the grate instead of the form described, provided that the grate can be tilted at an angle backwardly or forwardly, thereby increasing or reducing, as the case may be, the available space for the updraft behind the canopy of the fireplace, (represented on the drawings by L.) The bottom of the grate. may bear a plate N, and the supports Gr may be united by a convex plate 0, the objects of such plates being to prevent the draft reaching the fire-bars H from the rear. A baflieplate may be hinged behind said canopy, worked automatically by the movement of the grate with connecting-links or by an independent handle actuated from the front of the stove.

An advantage of my invention is that the orifice leading into the flue or chimney can be varied in size by tilting the grate. Thus when the fire is first lighted and tending to be smoky the grate and back can be tiltedand the smoke will have more room to escape.

Also when in this position the fuel tends to keep in a compact mass. When the grate is tilted forward, the rate of combustion is slower, and the fuel, which will now have become incandescent or well heated, will generally become spread over a greater area. The heat-radiating back will deflect its accumulated heat forwardly and slightly downwardly from the front of the fireplace, and the gratebottom will lie upon the ash-box, and therefore practically no air will be able to pass through the fire from underneath until, if

needed, the box be pulled forward slightly or the grate raised a little on its pivots.

I do not limit my invention to the particular form of bearing for supporting the grate as shown, for it is obvious that ahinge of different type would answer, or the crescent pieces F may rest upon a fiat edge, thus acting as rockers. The particular arrangement shown, however, provides sufficient friction to cause the grate to remain at any desired angle.

What I claim is 1. A fireplace or fire-grate in which the back is rigidly connected to the bottom, so

that the latter will move radially to an inclined or horizontal position while the back is swung rearward or forward, the angle between them remaining the same.

2. A fireplace or fire-grate mounted upon a hinge or bearings whereby it can be tilted and the orifice leading into the flue or chimney thus varied in size.

3. In a fireplace means for regulating combustion comprising having a. back B, a front rail E and sidfl elattercarrying pivotal members F, sup G for said members, the fire-bars H, and the ash-box J 10- cated below said rail and fire-bars.

In testimony whereof I' have hereunto set my hand in the presence of two witnesses.
